transfer from Yola to Worpress

Hello, I am currently using Yola.com as my website host/builder. Since my website is a local news source that has been growing in the past months, I wanted to give it a more professional look so I can interest buyers of my marketing services. So in the following weeks, I wanted to change to another host in which I would have the opportunity to have a more professional news-like template. My question is, can I create a easy to use blog site with WordPress in which I can transfer my domain without interrupting my source. If so, how long would it take to transfer to this host? I appreciate an urgent response. Best Regards.
